GeForce GTX 460 768MB is a high-end GPU based on the 40nm Fermi architecture. It's based on the Fermi GF104 Core and offers 336 Shader Processing Units, 56 TMUs and 32 ROPs, on 192-bit memory interface of fast GDDR5. The central unit runs at 675MHz and the memory clock operates at 900MHz. Compared to the reference GeForce GTX 460, it offers less memory bandwidth and a smaller frame buffer. Benchmarks indicate that its performance might be up to 8% worse than the standard version. Most modern demanding games will run at the highest settings using a 1080p resolution. However, some will require reduced settings to be played optimally.

Will my PSU power it I have 0 6pin or 6+2 pin but I have 2 molex. Then i will use 2x (molex-2xmolex) splitters and then use 2x (2xmolex to 6 pin). My psu http://www.inter-tech.de/index.php?option=com_content&view=article&id=112%3Asl-500&catid=49%3Aatx-netzteile&Itemid=153&lang=en
